WALTER E. ROBISON AND CHARLES KAISER, OF TRENTON, NEW JERSEY, ASSIGITORS TO WILLIAM HEAP & SONS, A FIRM CONSISTING" OF WILLIAM I'IEAP, WILLIAM LIONEL HEAP, AND CECIL R. HEAP, 0F GRAND HAVEN, MICHIGAN.

- LEVER-OPERATING MECHANISM.

Application filed May 1, 1913.

To all whom it may concern Be it known that we, WALTER E. RoBIsoN and CHARLES KAIsER, citizens of the United States of America, residing at Trenton, in the county of Mercer and State of New Jer= sey, have invented certain new and useful Improvements in Lever-Operating Mechanism, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to lever mechanism for flushing valves and has among the objects thereof to provide a simple and efiicient lever mechanism that may be easily and cheaply manufactured; further to provide v a device in which a single support carries the parts of the lever mechanism positioned Within the tank, thereby reducing the number of points of attachment between the tank and lever mechanism to a minimum.

Other objects of the invention will more fully hereinafter appear.

The invention resides in the peculiar construction, arrangement and combination of parts as hereinafter set forth and particularly pointed out in the claims.

In the drawings ;Figure 1 is a perspective view of the device embodying the invention; and Fig. 2 is asection on the line ww of Fig. 1, showing the device attached to the wall of the tank.

A designates the rod of the flushing valve and B a lever having a lateral extension C at one end connected to the rod A, the lever being fulcrumed, preferably intermediate its ends, for rocking movement about its longitudinal axis, upon a support D. In the structure illustrated in the drawing the support is provided with spaced ears E F having alined apertures G H within which the lever is arranged for oscillatory movement. The inner end of the lever isprovided with spaced bearings I J, herein shown as formed by bending the inner end into a laterallyextending U-sha-ped portion. Preferably the lever is formed of a round rod of bendable material, so as to permit one end of the rod to be inserted through the apertures G H and then bent into the .form desired.

K is an operating shaft extending through Specification of Letters Patent.

the wall L of the tank, M a handle secured to the outer end of the operating shaft, and N an actuating member for the lever. As shown, the bearings I J are arranged upon opposite sides of the axis of the shaft K and the member N is provided with laterallyextending arms 0 P positioned upon the same side of the bearings I J, preferably therebeneath.

By the arrangement before described, when the handle M is moved in one direction the arm 0 will engage the bearing '1, rocking the lever B about its longitudinal axis and raising the outer end of the extension C. Likewise when the handle is moved in the opposite direction the arm Pwill contact with the bearing J and likewise rock the member B. It will be noted that irrespective of the direction in which the handle M is moved, the lever B is rocked through the same leverage.

In order to reduce the number of points of connection between the lever mechanism and the tank, the support D is carried by the bushing or bearing for the operating shaft. As shown, the shaft is j ournaled in a sleeve Q that passes through an opening R in the Wall of the tank. This sleeve is exteriorly threaded and the support D is provided with a threaded eye S which has a'threaded engagement with the portion of the sleeve that projects within the tank. Upon the outer end of the sleeve is arranged a nut T which serves not only to clamp the eye S against the inner face of the tank, but also to close the outer end of the sleeve. Preferably a washer U is interposed between the nut T and the outer face of the tank wall. If desired the eye S may be provided with a portion V of non-circular cross-section that seats within a recess V of similar shape. If it is desired to .vary the leverage between the lever B and the member N, this may be accomplished by adjusting the sleeve R inwardly or outwardly as desired, in relation to the wall L, since such a movement of the sleeve will correspondingly adjust the member N inwardly or outwardly, thereby ilraj'ying the operating length of the bearings abutment for the ends X Y, preventing longitudinal movement of the lever B. The outward movement of the U-shaped portion is limited by means of a lug A on the support, positioned to engage the portion I before the U-shaped bearing portion passes beyond its vertical position, thereby avoiding accidental damage to the flushing valve, which might be caused by too great a movement of the extension 0.

While a very desirable form of the invention has been shown, it is not desired to limit the protection to the particular structure illustrated, since the invention is considered of suflicient scope to embody various modifications.

'What we claim as our invention is 1. In a lever mechanism for flushing "alves, the combination of a lever mounted to rock about it longitudinal axis and'having a lateral valve actuating extension, an operating shaft arranged to turn about an axis at substantially right angles to the longitudinala-xis of said lever, and a connection between said shaft and said lever'for rocking the lever in the same direction upon a movement of the shaft in either direction.

2. In a lever mechanism for flushing valves, the combination of a lever mounted to rock about its longitudinal axis provided with a lateral valve actuating extension, a rotatable operating shaft arranged to turn about an axis at substantially right angles to the longitudinal axis of said lever, and a connection between said shaft and said lever for rocking the lever in the same direction and through the same leverage upon a movement of the shaft in either direction.

.3. In a lever mechanism for flushing valves, the combination of a support, a lever mounted upon the support to rock about its longitudinal axis and having a lateral valve actuating extension, an operating shaft arranged to turnabout an axis at substantially right angles to the longitudinal axis of said lever, and an actuating member carried by the shaft and positioned in operative relation to the lever for rocking the latter in the same direction upon a movement of the shaft in either direction.

4. In a lever mechanism for flushing valves, the combination of a support, of a lever mounted .intermediate its ends upon a support, to rock about its longitudinal axis, said lever having a lateral valve actuating extension adjacent its outer end and being provided with spaced bearing portions adjacent its inner end, an operating shaft arranged to turn about an axis at substantially operating shaft arranged to turn about an axis at substantially right angles to the longitudinal axis of said lever, and means actuated by said shaft for respectively engaging said spaced bearing portions upon the movement of the shaft in opposite directions. I

6. In a lever mechanism for flushing valves, the combination of a lever mounted to rock about its longitudinal axis and having a laterally-extending valve actuating 7 portion, an operating shaft arranged to turn about an ax1s at substantially right angles to the longitudinal axis of said lever, a connection between saidshaft and said lever for rocking the lever in the same direction upon a movement of the shaft in either direction, and means for limiting the rocking move ment of the lever. Y i r 7. In a lever mechanism for flushing valves, the combination'of a support, of a lever mounted thereon to rock about its longitudinal axis and having a lateral valve actuating extension, an operating shaft arranged to turn about an axis at substantially right angles to the longitudinal axis of said lever, a connection between said shaft and said lever for rocking the lever in the same direction upon a movement of the shaft in either direction, and means carried by the support for limiting the rocking movement of the lever in one direction.

8. In a lever mechanism for flushing valves, the combination of a support provided with spaced bearing portions, of a lever journaled in said spaced bearing portions to turn about its longitudinal axis, said lever having a laterally-extending valve actuating portion and being provided with spaced bearings, an operatingshaft arranged to turn about an axis at substantially right angles to the longitudinal axis of said lever, and an actuating member carried by said shaft having laterally-extendingarms positioned in operative relation to said bear ings. I j
